Delimiter Configuration

You can configure delimiters to split log content into words, so you can search for logs by these words. LTS has preconfigured the following delimiters:

, '";=()[]{}@&<>/:\n\t\r

If the default delimiters cannot meet your needs, you can set custom delimiters.

This function is available only in regions AF-Johannesburg, AP-Singapore, CN-Hong Kong, CN East-Shanghai1, LA-Mexico City1, LA-Mexico City2, LA-Santiago, and LA-Sao Paulo1.

Precautions

Your custom delimiters are applicable only to the log events generated after the delimiters are configured.

Procedure

Log in to the LTS console, choose Configuration Center in the navigation pane on the left, and click the Delimiters tab.
Configure delimiters.
You can configure delimiters in either of the following ways. If you use both ways, the delimiters configured in the two ways will all take effect.
- Common Delimiters: Click Edit and enter delimiters in the text box.
- ASCII Delimiters: Click Edit. On the displayed page, click Add ASCII Delimiter and enter ASCII values by referring to ASCII Table.
Preview the parsing result.

Enter log content in the text box and click Preview.
Check whether the parsing result is correct. If it is correct, click Save.
You can click Reset to restore the default delimiters, which include:
```
, '";=()[]{}@&<>/:\n\t\r
```
